The Rochester family's first well known official boss was Constenze "Stanley" Valenti. In 1957, after the Apalachin Conference, Stan and his brother Frank were both jailed for civil contempt, because they refused to answer questions about the meeting. In 1958, Stan was sentenced to 16 months in prison, and Jake Russo became the next boss.[1][2]

In 1964, Frank Valenti returned to Rochester with his brother Stan, and Pittsburgh associate Angelo Vaccaro. Frank became an associate in the Pittsburgh crime family in John LaRocca's family. Stan Valenti was married to Antonio Ripepi's daughter, who was a capo in the Pittsburgh family. This time, Frank Valenti was taking over the Rochester family. By the end of the year, Russo went missing and his body has never been found. In 1970, Valenti wiped out the last Russo soldier Billy Lupo. Also Frank Valenti told Buffalo crime family boss Stefano "The Undertaker" Magaddino that Rochester would become an independent family. Prior to this, Rochester was just a crew which answered to the Maggadino's Buffalo crime family.

Valenti created a well organized crime family by promoting Samuel Russotti to underboss, Rene Picarreto to consigliere and Salvatore Gingello, Dominic Celestino, Thomas Didio, Angelo Vaccaro and Dominic Chirio as his capos.[1] His most trusted ally was capo Chirio, who he gave special tasks to carry out. He divided up the family's illegal activities of gambling, extortion, loan sharking, insurance fraud, arson, narcotics and weapon trafficking among his capos to ensure peace.

Valenti created a master plan in 1970 called "The Columbus Day Bombings". He set up a special crew to bomb various churches and public buildings to draw the heat away from the family. In 1972, Valenti was approached by his underboss Samuel "Red" Russotti, his consigliere Rene Piccarreto, and highly powerful capo Salvatore "Sammy G" Gingello. The three accused Valenti of skimming profits and asked him to step down as boss; he refused. Valenti felt that the Pittsburgh family would back him and the Chirico crew up with muscle. Unknown to him was that his consigliere, Picarreto, had made a secret alliance with members of the Bonanno crime family. Valenti's most trusted capo and bodyguard, Domenic Chirico, was shot and killed on Augustine Street. Instead of fighting he was allowed to move to Phoenix, Arizona and retire. After retiring Valenti was arrested and convicted of extortion, [1] he later died on September 20, 2008.

After Valenti fled the city, Samuel Russotti became boss, Piccarreto remained as consigliere, and Gingello became the underboss. The family was strong until January 1977 when the police fabricated evidence to indict all the upper echelon. The convictions put Russotti, Piccaretto, Gingello, Thomas Marotta and Eugene DeFrancesco away for murdering Vincent Massaro with a 25 years to life sentenced. When this happened, Thomas Didio became the acting boss. Russotti thought he would be able to manipulate Didio, but he really just created a monster. Didio began demoting all the Russotti loyalist while receiving advice from imprisoned former boss Valenti. When the truth came out about the fabricated evidence, all the top guys got out of prison. This created an "A team and B Team" war. Part of the "A team" was Russotti, Piccarreto, Gingello, Richard Marino, Thomas Marotta and others. Part of the "B Team" was Thomas Didio, Rosario Chirico (Domenic's brother), Stan Valenti, Angelo Vaccaro and others.[1]

On April 23, 1978, Salvatore "Sammy G" Gingello was killed when a bomb was detonated when he entered his car. On July 6, 1978 Thomas Didio was murdered by a gunman who was using a machine gun. After these two murders the FBI decided it was time to crack down on the situation, with RICO coming into play they took down most of the remaining key players. In 1988, Angelo Amico and Loren Piccarreto were both indicted under the Racketeer Influenced and Corrupt Organizations Act (RICO). Angelo Amico was the acting boss, and Loren Piccarreto (son of Rene Piccarreto) was the underboss.[1]

Though mostly driven underground, the Rochester mafia is still actively engaged in its root operations, but also thriving through high-tech crimes and frauds. Members are somewhat more loosely structured and function more as satellite groups. Younger, up-and-coming members made their reputations in the Rochester and Buffalo chapters through cigarette sales, sophisticated thefts and computer crimes. Operations under the store Unlimited Gold are still active and running today. [3]

After the conviction of the top members in 1988 the family's criminal activity declined. In 1993 imprisoned boss Samuel Russotti died. Months later Angelo Amico and Loren Piccarretto were released from prison. There has been no further evidence that the Rochester crime family is still active.[2]
